MIXING APPARATUS.

, T 0 all whom it may concern:

Be it known that I, DAVID B. JACKSON, a citizen of the United States, residing at Clarendon, in the county of Monroe and State of Arkansas, have invented a new and useful Mixing A paratus, ofwhich the following is a speci cation. v

This invention is an apparatus designed more particularly for mixing drinks, and its aim is to provide in an apparatus of this kind, a novel form of motor driven beater,

together with. novel and improved means for throwing the beater into and out of operation, a longitudinally, movable beater shaft being provided which is operatively connected to the motor shaft by pressure against said beater shaft of the glass or other receptacle containing the liquid to be mixed.

The invention also has for its object to provide a mixing apparatus of the kind stated which'is simple in construction, and devoid of complicated parts, and to this end the invention consists in a novel construction and arrangement of parts to be hereinafter described and claimed, reference being had to the drawing hereto annexed in which- Figure 1 is a side elevation of the apparatus'. Fig. 2 is a front elevation partly broken away.

Referring to the drawings, the supporting frame of the machine comprises a base 5 from which rises a column or standard '6 havin at its upper end a forwardly presente portion 7 provided with a bearing forthe shaft 8 of the beater 9. To the standard 6 is also clamped or otherwise secured a shelf or bracket 10 on which the motor 11 is supported.- The outer end .of the shelf is also provided with a bearing for the beatershaft 8 and has a depending tubular portion 12 through which-the shaft extends. The

fittedwith a collar 131w ch'abuts a ainst the top of the shelf 10 b which the ownward movement of thes aft is limited, the shaft being yertically presented -and also beater shaft 8 is verticallypresented andis movable lengthwise in its bearings, for a purpose to be presently described; T 1e heater 9 maybe of any form best adapted for the purpose for w ower end of the-shaft'1'8 in an suitable manner'.. The lower end-of the'tu lai' por-H icli the 'ap-- aratus is designed, and it..1s. secured to the Specification of Letters latent. Patented NOV. 23, 1909. I Application filed February 17, 1909. Serial No. 478,450.

- slightly below the'beater. The beater shaft v8 extends for a short distance below the beater as indicated at 15, which is for a purpose to be presently made clear. 3

The motor 11 in the present instance is anelectric motor,'and its-shaft 16 is fitted with a friction disk 17 adapted to engage afriction disk 1 8 on the beater shaft 8.

At l9 is. indicated diagrammatically a suitablesource-ofelectric energy one side of which is grounded on the supporting frame of the apparatus by means of a conductor 20 connected thereto, and the other side 'is' connected by a conductor 21 to one of the binding posts 22 of the motor. On the portion 7 of, the supporting frame is mounted a contact -spring 23 which .is connected by a conductor 24 to the. other bindingpost 25 of the motor. The contact :sprmgis i'nsu- '75 lated from the frame by' a strip of insula-' tion indicated at 26. The free end of the contact spring is in the .path of the-upper end of thebeater shaft 8, in order that the latter may make contact therewith, and thus close the circuit of the'motor. When contact is thus made, the circuit may be traced through the conductor 20, supporting frame of the apparatus, shaft 8-, contact spring 23, and conductor 24; to the binding 85.

post 25, and from binding post 22 by conductor 21 to the source. I

The operation of th apparatus is as follows: The disks 17 an 18 are normally out of contact, and the contact between the shaft 8 and the contact spring 23 is alsobroken. Upon placing the lass or other receptacle containing" the 'liqu1d to be mixed over the beater 9, and forcing the glass upwardly until .its bottom comes in contact with the lower end 15 of the shaft 8, and then .pressing upwardly onv the shaft by ftheglass till the dlsks 17and118.-are, incontact, and the upper endof the shaft 8. makes contact with tor is closed, an it"-no wv being also geared to the beater shaft',*throu"ghthe disks 17 and the contact sprin 2 3,' the circuit to the mo:

18,-said shaft is rotated, andfthe beater is; actuated. on; lowering the -glass, the shaft drops o,wn"a in, andgthej disks I7;

beater shaft from thefm torfshaft; the

thus-"opened, If desired suitable'pmdtor may be rovi-ded,--- in"'whiel1 .case ;-.theelectric connections i of course, are

and 18 separate; t us decent-seam.- the dispensed with, the apparatus being thrown into and out of operation by. the engagement and disengagement of the disks 17 and 18 only.

It will be seen from the foregoing that I have provided a mixing apparatus which is simple 'in construction and which has no complicated parts to get out of order, and by the driving mechanism employed the apparatus is easily operated, it being necessary only to insert the beater 1nto the glass, and

press upwardly on the beater shaft by the' latter.

What is claimed is:

1. A mixing apparatus comprising a supporting frame, a longitudinally -m ovable shaft mounted therein, a beater carried by the shaft, a motor and its drive shaft, and gearing between the beater and motor shafts, said gearing being normally disconnected. I

2. A mixing apparatus comprising a supporting frame, a longitudinally movable shaft mounted therein, a beater carried by the shaft, a friction disk on the shaft, a motor and its drive shaft, and a friction disk on the drive shaft engageable with the friction disk of the beater shaft, said disks being normally disconnected.

3. A mixing apparatus comprising a sup porting frame, a longitudinally movable shaft mounted thereon, a beater carried by the shaft, an electric motor and its drive shaft, gearing between the beater and motor shafts, said gearing being normally disconnected, a contact spring mounted on the supporting frame in the path of the beater shaft,'and an electric-circuit adapted to be closed by the engagement of the beater shaft with the said contact spring.

4:. A mixing apparatus comprising a supporting frame, a, longitudinally movable shaft mounted therein, a beater carried by the shaft, an electric motor and its. drive shaft, a normally open electric circuit to whlch themotor 1s connected, gearing between the beater and motor shafts, said gearing being normally disconnected, and meansfor s multaneously connecting said gearing, and closing the circuit.

In testimony that I claim the foregoing as my own, Ifhave hereto affixed my signature in the presence of two witnesses.
